Abstract

An illumination apparatus for a vehicle accessory is disclosed. The apparatus comprises a lighting device disposed proximate the vehicle accessory comprising a persistent luminescent portion. The persistent luminescent portion is configured to charge in response to an excitation emission from a light source. The apparatus further comprises a detection sensor configured to detect a device proximate the vehicle and a controller configured to activate the light source in response to the detection. The light source is configured to charge the persistent luminescent portion to emit an output emission.

Claims

1. An illumination apparatus comprising:

a lighting device disposed proximate a vehicle accessory comprising a persistent luminescent portion configured to charge in response to receiving an excitation emission comprising a first wavelength from a light source;

a detection sensor configured to detect a device proximate the vehicle; and

a controller configured to activate the light source in response to the detection to charge the persistent luminescent portion to emit an output emission comprising a second wavelength.

2. The illumination apparatus according to claim 1, wherein the detection sensor corresponds to a wireless radio transceiver in communication with the controller.

3. The illumination apparatus according to claim 2, wherein the detection sensor is configured to detect an approaching occupant by detecting a communication of the device via the wireless radio transceiver.

4. The illumination apparatus according to claim 3, wherein the controller is configured to identify that the occupant is approaching the vehicle based on a proximity profile of the device.

5. The illumination apparatus according to claim 4, wherein the controller is configured to charge the persistent luminescent portion in response to the detection of the approaching occupant.

6. The illumination apparatus according to claim 1, further comprising a global positioning device configured to identify a position of the vehicle in communication with the controller.

7. The illumination apparatus according to claim 6, wherein the controller is configured to identify a location where the vehicle is parked for a predetermined period of time based on the location from the global positioning device.

8. The illumination apparatus according to claim 1, further comprising a door sensor in communication with the controller, wherein the door sensor is configured to identify an ajar status of a door of the vehicle.

9. (canceled)

10. An illumination apparatus for a vehicle accessory comprising:

a lighting device disposed proximate the vehicle accessory comprising a persistent luminescent portion configured to charge in response to receiving an excitation emission;

a light source configured to emit the excitation emission;

a location detection device configured to detect a location of the vehicle; and

a controller configured to activate the light source in response the location of the vehicle approaching a parking location.

11. The illumination apparatus according to claim 10, wherein the controller is configured to detect the parking location in response to the location detection device identifying that the vehicle is parked in the parking location for a predetermined period of time.

12. The illumination apparatus according to claim 10, wherein the controller is operable to identify that the vehicle is approaching the parking location in response to the location of the vehicle being within a predetermined distance of the parking location.

13. The illumination apparatus according to claim 12, wherein the controller is further configured to charge the persistent luminescent portion to emit an output emission in response to the identification that the vehicle is approaching the parking location.

14. The illumination apparatus according to claim 10, wherein the controller is further configured to activate the excitation emission from a time period when the vehicle is within the predetermined distance to a time when the vehicle is parked proximate the parking location thereby charging the persistent luminescent portion.

15. The illumination apparatus according to claim 10, wherein the excitation emission corresponds to a first color of light and the output emission corresponds to a second color of light different from the first color.

16. The illumination apparatus according to claim 10, wherein the lighting device comprises a first light generating layer printed in a first liquid suspension configured to emit the excitation emission.

17. The illumination apparatus according to claim 10, further comprising a light sensor in communication with the controller configured to communicate an ambient light signal to the controller to control the intensity of at least one of the excitation emission.

18. An illumination apparatus for a vehicle accessory comprising:

a lighting device disposed proximate the vehicle accessory comprising a persistent luminescent portion configured to charge in response to an excitation emission from a light source and emit an output emission;

a wireless radio transceiver configured to detect a mobile device proximate the vehicle; and

a controller configured to activate the light source in response to the detection thereby charging the persistent luminescent portion.

20. The illumination apparatus according to claim 18, wherein the excitation emission corresponds to a first color of light and the output emission corresponds to a second color of light different from the first color output in response to the persistent luminescent portion receiving the excitation emission.

21. The illumination apparatus according to claim 18, wherein:
